Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning outdoor unit accessories, in particular to a central air-conditioning outdoor unit maintenance support frame. Background Art

[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from traditional refrigerant air conditioning. It centrally processes air to meet comfort requirements and uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. The outdoor unit of the central air conditioner is placed outdoors, and the outdoor unit of the air conditioner is also called the main unit.

[0003] The existing patent CN220567495U discloses a central air-conditioning outdoor unit maintenance support frame, which relates to the field of central air-conditioning outdoor unit accessories, including a mounting frame that can be installed on the rear side of the central air-conditioning outdoor unit, a bracket that can carry the central air-conditioning outdoor unit is arranged below the mounting frame, and a movable linkage frame is arranged on the front side of the bracket, and the surface of the linkage frame extends outward to form a plurality of alignment plates. In a natural state, the plurality of alignment plates are all located on the inner side of the recessed part of the bracket surface. The utility model can extend and expand the load area of ​​the bracket while ensuring the original stable state of the bracket, so as to facilitate the operation of tipping the central air-conditioning outdoor unit and performing maintenance operations. The stability of the central air-conditioning outdoor unit during tipping and maintenance operations is ensured, and there is no need to carry the central air-conditioning outdoor unit, which has the advantage of portable operation. The stop block with adjustable position has a limiting effect on the support rod at the bottom of the linkage frame, so as to prevent the linkage frame and the alignment plate from shaking or deflecting.

[0004] Based on the search of the above patents and in combination with the support frame in the prior art, it is found that the above support frame can be extended through the bracket to extend the support area, which is convenient for the tilting and maintenance of the air-conditioning outdoor unit and easy to operate. However, in actual use, the extension and fixation of the bracket need to be operated in conjunction with four linkage screws. For the movement and fixation of the bracket, the linkage screws on both sides need to be adjusted, which is a cumbersome process. In addition, the linkage screws are used in outdoor environments for a long time and are eroded by rain, which can easily cause thread rust damage, resulting in damage to the linkage screws, making them ineffective, thereby reducing their practicality.
